Aquatic plants need more potassium to adapt to the new environment and take root. Therefore, it is suggested to add potassium fertilizer (half of the dosage) every day on the second day of planting grass in the new cylinder. After aquatic plants adapt to the rapid growth of water quality, they can reduce their daily dosage or increase their frequency as appropriate.

Fast-growing green-positive aquatic plants such as mini-dwarf, ear-digging, coriander and coriander have great demand for potassium. If there is obvious potassium deficiency such as yellow and white leaves, after the symptoms of potassium fertilizer application disappear, the daily dose or frequency of potassium fertilizer application can be reduced as appropriate.

Lighting time setting

In the first week, the illumination time is about 3 ~ 4 hours, so the aquatic plants are still adapting to the environment and don't need much illumination. If the illumination time is too long, algae are easy to breed.

In the second week of cylinder setting, the lighting time can be increased to 5-6 hours.

After the third week of cylinder setting, the lighting time can be gradually increased to the normal time, that is, 8–10 hour.

It is best to turn on and off the lights step by step. Don't turn on all the lights at once. Multi-stage switch is better and more in line with natural ecology. Aquatic plants have sleep time and must not be exposed to light for 24 hours.
